To limit the probability that the structural performance of floors-on-ground will fall significantly below expectations, which could lead to an inadequate resistance to gravity loads or lateral soil loads, which could lead to damage to floors or foundation walls.
This is to limit the probability of:
For floors and elements supporting floors, this is to limit the probability of excessive deflection and vibration of floors, which could lead to loss of balance, tripping or falling, which could lead to harm to persons.
